BOTTLE CAP OR CLOSUREFOR BOTTLES, JARS, 86C.

SPECIFICATION forming part of Letters Patent No. 726,451, dated April 28, 1903.

Application filed December 20,1902. Serial No. 136,080. (No model.) 7

' other vessels of glass or other material.

The object of my invention is to provide a sheet-metal bottle cap or closure of a simple and efficient construction, which may be cheaply manufactured, readily and conveniently applied to the bottle, jar, or other vessel, which will securely seal the bottle, jar, or othervessel, and which at the same time may be easily opened by a simple instrumentsuch, for example, as an ordinary nail.

My invention consists in the means I employ to practically accomplish this object or result-that is to say, it consists, in connection with a bottle, jar, or other vessel having a cap holder, shoulder, or groove at its mouth or open end and a cork or sealing-disk of some impervious and compressible material-such, for example, as corkof a sheet metal corkholder disk which fits on top of the cork or sealing-disk, and a sheet-metal clamp-disk having a depending segmental or divided crimping-flange adapted to be smoothly and closely crimped or bent into the groove or under the shoulder of the mouth of the bottle, jar, or vessel and provided with an integral raised portion extending diametrically across the same and forming a socket or groove into which a nail or other simple instrument may be inserted for wedging or prying off the clamp-disk, and thus opening the bottle, jar, or vessel. The entrance or openinginto this groove or socket coincides with the segment or circumferential part of the clamp-disk, Where its crimping-flange is omitted, notched, or divided, so that the whole extent of the wedging or prying force of the nail or instrument tending to open or raise the clamp-disk comes first upon 'the free or end edges of the crimping-flange, and thus tends to spread the same and enables the clamp-disk to be readily started in its opening movement. This is further facilitated by the inclined or rounded shape of the end edges of the crimping-flange on the clamp-disk in connection with the rounded shoulder of the bottle, jar, or vessel, which gives a cam-like; inclined, or wedging action in outwardly bending or spreading the crimping-flange in its initial or starting movement. The cork-holder disk is provided, or preferably provided, with a short segmental crimping flange at the notch, division, or opening in the crimping-flange of the clampdisk, the two segmental crimping-flanges on the cork-holder disk and clamp-disk thus supplementin g each other and substantially completing the circle, so that the cork or sealingdisk may be compressed and held compressed by the crimping-flanges at the whole circumference, if desired.

In the accompanying drawings, forming a part of this specification, Figure 1 is a front elevation of a cap or closure embodying my invention and showing the same as applied to a bottle. Fig. 2 is a plan view. Fig. 3 is a central vertical section on line 3 3 of Fig. 1. Fig. 4 is a central vertical section on line 4. 4 of Fig. 3. Fig. 5 is a detail plan of the corkholder disk. Fig. 6 is a section of same on line 6 6 of Fig. 5, and Fig. 7 is a detail sec tion of the clamp-disk.

In the drawings, A represents a bottle, jar, or other vessel, having at the mouth of its neck a cap-holder groove'or shoulder a.

O is the cork or sealing-disk, the same being made of any suitable impervious and compressible sealing material-as, for example,a thin disk or cork or other suitable natural or artificial material commonly used for this purpose.

B is the sheet-metal cork-holder disk, the same having a narrow depending retainingfiange b for keeping or holding the cork or sealing-disk in place therein. It is also provided with a short segmental depending crimpingfiange 1), preferably about three-eighths of an inch in length and of slightly-larger diameter than the cork-retaining flange b, so that it may properly fit over the beveled or rounded cap-holder shoulder a of the bottle, jar, or vessel.

D is the clamp-disk, the same having a depending segmental crimping-flange d extending, preferably, all around the clamp-disk excepting about three eighths of an inch,

' has rounded or inclined ends 61 to facilitate the wedging or prying off of the clamp-disk. This action is also aided by the rounded shape a of the cap-holding external shoulder a on the bottle, jar, or vessel. The clampdisk D has extending diametrically across the same an integral raised portion 01 forming a groove or socket d to receive a nail or other simple instrument for prying olf or wedging off the clamp-disk. The entrance d in the clamp-disk to this groove or socket d is preferably adjacent to the notch or division d'in the crimping-flange d, so that the initial prying or wedging force of the instrument in opening the vessel may be exerted upon the notched, divided, or weakened portion of the crimping-flange d.

In operation the cork or sealing-disk C.- is permanently applied to the sheet-metal corkholder disk 13 at the time the device is manufactured. To seal the bottle, jar, or vessel, the cork-holder disk, with the cork therein, is placed on the mouth or open end of the ves sel with the clamp-disk inclosing or embracing the same, and then the cork or sealingdisk is compressed by downward pressure thereon, so as to tightly seal the bottle, jar, or vessel, and then while held so compressed the segmental crimping-flanges on the clampdisk and cork -holder disk are crimped or bent under the cap-holder shoulder a on the bottle, jar, or vessel. To open the bottle, jar, or vessel, a nail or other simple instrument, as F, is inserted in the groove or socket d between the clam p-disk and cork-holder disk, and the clam p-disk wedged or pried off, enabling the cork-holder disk and cork or sealing-disk to be removed. The cork-holder disk B is preferably provided with the narrow retaining-flange b, as illustrated in the drawings, as this is aconvenience in keeping the cork or sealing-disk in position prior to the assembling of the two disks'B and D together, especially in cases where the cork'or sealing-disk is composed of a plurality of elements. The narrow flange b may, however, be omitted, if desired, as the cork-holder disk without this flange will give proper support to the cork or sealing-disk and to the nail or implement used in wedging or prying off the clamp-disk.

I claim 1. The combination with a bottle, jar or vessel, having a cap-holder shoulder at its mouth or open end, of a cork or sealing-disk, a cork-holder disk B having a flange b and a short segmental depending crimping-flange b, and a clamp-disk D having a depending segmental crimping-flange d supplementing the crimping-flange on the cork-holder disk, and provided with an integral raised portion forming a socket or groove for insertion of a nail or other simple instrument between the cork-holder disk and clamp-disk for wedging or prying oh" the clamp-disk and opening the bottle, jar or vessel, the entrance to said groove or socket coinciding with the notch or divided portion of said crimping-flange on the clamp disk, and the segmental crimpingflange on the clamp-disk having rounded or inclined ends, substantially as specified.
